This document describes how to set up
the Vickers 30 design proportional valve
power amplifiers.
The Eurocard type amplifiers covered in
this procedure are listed below. More
detailed information on the power
amplifiers can be found in Vickers
catalog GB-C-2007C.

EEA-PAC-2007C for more detailed
information on these power amplifiers.
This is an easy-to-use procedure for
anyone with a little understanding of
how proportional valves work.
Proportional valve solenoids are current
controlled. This current is usually
regulated by varying the command
voltage into the amplifier. The greater
the current to the solenoid coil, the
greater will be the valve spool

This document does not deal with valve
sizing. However, it should be recognized
that proper sizing will directly affect the
control of acceleration and deceleration.
Select the smallest valve size possible

valve size. This results in pressure drop
